Summary: the department of otolaryngology at mount sinai is looking for adults with sinus disease with polyps, otherwise called chronic rhinosinusitis with nasal polyps (crswnp). patients may be eligible to enroll in a study offering a cutting-edge therapy to help reduce symptoms and avoid surgery. the treatment combines an antibiotic (doxycycline) with oral steroids. oral steroids are the mainstay of medical management for patients with crswnp. however, recent studies have shown that doxycycline helps improve symptoms as well by reducing inflammation and killing common bacteria that can cause symptoms. this study is the first to evaluate this combination regimen.

an eligible patient may be treated with either doxycycline and oral steroids or placebo (sugar pill) and oral steroids for three weeks. volunteers will participate in the study for to 12 weeks, and will have 4 research visits of 1 hour duration. at each study visit, the patient will under go an endoscopic evaluation and asked to complete a questionnaire describing symptoms. there is no additional cost to be enrolled in the study.
